Attached v3 with pg_usleep called instead.

Hmmm.... you've got a point, although I'm not sure how it could work 
without sleeping explicitely. Maybe the path was calling select with an 
empty wait list plus timeout, and select is kind enough to just sleep on 
an empty list, or some other miracle. ISTM clearer to explicitely sleep in 
that case.
